Writing and drawing are understudied with fMRI, partly
for lack of a device that enables realistic approximation of this behavior,
including task performance feedback and quantitative behavioural logging in the
confines of the magnet. Therefore, we developed a tablet based on touchscreen technology
that is accurate, reliable, and relatively inexpensive. In a preliminary fMRI
experiment, we examined the neural correlates of a widely used pen-and-paper
neuropsychological assessment, the Trail Making Test. The results were similar
to the major results of a previous group study, which encourages us to extend
the experiment and to continue developing the tablet.
